“…The S BET was augmented from 12 to 15 m 2 g -1 after loading MCS onto surface of NiSe 2 , this was because the cubic NiSe 2 provide enough space for anchoring of MCS nanoparticles, which effectively prevent the occurrence of agglomeration. In addition, the increased surface area of composite catalyst MCNS-10 exposing more activity sites, which enhancing photocatalytic hydrogen evolution performance [43]. In short, the change of S BET of MCNS-10 was consistent with the alter in morphology for MCNS-10 composite in TEM images.…”

“…Generally, the electron lifetime was negatively correlated with electron transfer rate. The consequences show that the electron transit time of MCNS-10 composite is short [47], this was because NiSe 2 could provide additional decay channel to the excited states of the MCNS [43]. We further studied the catalyst performance from two aspects values of electron transfer rate constant (K ET ) and the electron injection efficiency (η inj ).…”

A novel effective 0D/3D nanohybrids of Mn0.05Cd0.95S/NiSe2 photocatalysts, which are formed by Mn0.05Cd0.95S nanoparticles anchored on the outer surface of cubic NiSe2 in designed and prepared. The optimum hydrogen evolution rate of the Mn0.05Cd0.95S/NiSe2 composite is 14.3 mmol h-1 g-1, which is 7.5 times higher than that of single Mn0.05Cd0.95S. Structural analyses and experimental results reveal that a little amount of NiSe2 can remarkably improve the photocatalytic activity and the close contact of the 0D/3D composite catalyst also plays an important role. Furthermore, NiSe2 can not only as both an electron acceptor to capture electrons and inhibit the recombination of electron-hole pairs, but also provide sufficient active sites to facilitate the photocatalytic water-splitting reaction activity. This work demonstrates that low-cost NiSe2 is a promising co-catalyst for photocatalytic splitting of water to produce hydrogen.

“…MOF materials have been regarded as one of the most promising photocatalysts owning to their abundant active sites, large specific surface area, and short charge transfer distance. However, the poor visible light response of MOF is a huge obstacle to its further development [132,133] . Therefore, CdS with strong light absorption capacity was introduced by Zhang and Jin to improve the photocatalytic performance of MOF [16] .…”

Photocatalytic hydrogen evolution can effectively alleviate the troublesome global energy crisis by converting solar energy into the chemical energy of hydrogen. In order to realize efficient hydrogen generation, a variety of semiconductor materials have been extensively investigated, including TiO2, CdS, g‐C3N4, metal‐organic frameworks (MOFs), and others. In recent years, to achieve higher photocatalytic performance and reach the level of large‐scale industrial applications, photocatalysts decorated with transition metal phosphides (TMPs) have shone brightly because of their low cost, stable physical and chemical properties, and substitution for precious metals of TMPs. This Review highlights the preparation methods and properties associated with photocatalysis of TMPs. Moreover, the H2 generation efficiency of photocatalysts loaded with TMPs and the roles of TMPs in catalytic systems are also studied systematically. Apart from being co‐catalysts, several TMPs can also serve as host catalysts to boost the activity of photocatalytic composites. Finally, the development prospects and challenges of TMPs are put forward, which is valuable for future researchers to expand the application of TMPs in photocatalytic directions and to develop more active photocatalytic systems.

“…PMs are candidates of excellent photocatalysts due to the large amount of exposed active sites as well as accommodation of CDs as photosensitizers. To fully utilize the visible region of sunlight and improve charge separation ability, CQDs with up‐conversion property were commonly introduced into porous photocatalysts, such as porous TiO 2 , C 3 N 4 , and MOFs . For instance, in photocatalysis process of CQDs/ meso ‐Ti‐450 fabricated by mesoporous TiO 2 loaded with up‐conversion CQDs (Figure a), CQDs were excited by long‐wavelength light (λ>600 nm), and emitted shorter wavelength light which could further excite TiO 2 , producing photo‐induced electrons and holes.…”
